Leinster lost their opening game of the season last night after an injury time penalty secured the win for the Glasgow Warriors.
It finished Glasgow 22. Leinster 20.
The home side were cruising at the break with a 19-3 lead.
It looked as though there was no way back for Leinster, but the boys in blue scored two late tries through Jack McGrath and Tom Denton in the final 10 minutes to take a one point lead.
But an injury time penalty secured the win for last year's losing finalists.
